IMPROVEMENT IN METAL-CLAD WOODEN BLINDS.

Specication forming part of Letters Patent No. 127,736, dated J unc 11, 1872.

Specification describing Improvements in Metal-Clad Wooden Blinds, invented by WIL- LIAM E. BROCK, of the city, county, and State of New York.

This invention relates to shutter-blinds clad with iron for the purpose of rendering them tire-proof. It consists in a novel manner of securing the meta-l covering to the frame, whereby cheapness, strength, and durability are obtained, andthe 'use of solder entirely dispensed with; it also consists in a novel manner ot' forming the joints between the sections of the frame without the use of solder, whereby great firmness and strength are obtained.

In the accompanying drawing, Figure 1 is a face view of the lower portion of blind-frame constructed according to my invention. Fig.V

2 is a central section of the same. Fig. 3 is a transverse section ot' one of the stiles ot' the blind-frame, and Fig. 4 is a top view of the toe-piece forming the joints ot' the sections composing the frame.

Similar letters of reference indicate correspondin g parts in all the igures.

A A are the two upright stiles of the blindframe, and B the bottom stile thereof. These are' all made of wood with their ends beveled 0E at an angle of forty-rive degrees to form ruiter-joints, and each is covered with sheetiron, E, which may be galvanized, and simply foldedaround the stile, so that the edges lap along its inner side, as shown at c c. O C are toe-pieces, consisting of cast-iron plates, of a size to it between the matching ends which form the miter-joints of the stiles, and having their edges turned up to form sockets e e at right angles to each other for the reception ot the ends of the stiles, which they keep in proper relation to each other, both longitudinally and laterally, without mortises or tenons. A bolt, D, passing longitudinally through the bottom stile B, through the toe-pieces C C, and through the ends of the stiles AA, se-

cures the stiles within the toe-pieces and brings the joints up very tight. The head of this bolt and the nut which secures it are countersunk into the stiles A A, so as to be flush with their outer sides. The metal coverings E ot' the stiles are secured by their ends tting in the sockets in the toe-pieces C C. Those on the long upright stiles are further secured by the slat tenons b b passing through the lap c c, and by washers a a which surround the slat tenons between the ends ofthe slats G G and the lap c c of the covering, and which, by bearing against the lap, keep it closed and assist in securing the covering. The mortises or holes which form the bearings of the slat tenons are made through the lap of the covers E, and thereby a double thickness of metal is provided as a bearing for each tenon, besides a bearing in the wooden body ofthe frame.

'lhis construction of the metal-clad wooden blind-frame dispenses entirely with the use ot' solder, and so renders them more perfectly lire-proof, and besides this it makes a frame of very great strength and durability.

Claims.

1. Ablind havin ga metal-clad wooden frame, the metal covering of the sides ot' which is secured by the slats, substantially as herein described.

2. The combination ofthe metal covering E, folded on the blind-frame, as described, with the washers a a, the slats G G, and their tenons b b, substantially as and for the purpose herein set forth.

3. The toe-pieces C O, in combination with the stiles A A and B, and bolts D, substantially as and for the purpose specified.
